shows
the other devices used for the data collection in this research.
The rangefinder is used to survey all corners of a room and via Bluetooth tech-
nology this data is transferred into a laptop.
3 3D Modelling
There are many different spatial data models; some of these are categorized as:
constructive solid geometry (CSG), boundary representation (B-Rep), regular decom-
position, irregular decomposition and non-manifold structures (Ledoux and Gold
2007
).
